Low power design can be exploited at various levels, e.g., system level, architecture level, circuit level, and device level. This paper gives a brief overview of low power design principals, then focuses discussion on circuit level methods specifically state-of-the-art low power design techniques of clocking systems. Finally we discuss low power optimization techniques at system and architecture...
Power consumption is the bottleneck of system performance and is listed as one of the top three challenges in ITRS 2008. Low power design can be exploited at various levels, e.g., system level, architecture level, circuit level, and device level. This paper first gives a brief overview for low power optimization techniques at system and architecture level, then focus discussion on circuit level methods...
This paper presents an efficient decoder design for the LDPC codes in IEEE 802.15 standard. This decoder features by high parallel level, low message memory requirement and code rate flexibility. By processing 72 columns and 72 rows in parallel, it can reach a throughput of 2.8 Gbps to fulfill the standard requirement. Furthermore, the decoder supports three different code rates by employing flexible...
This paper presents two efficient decoder designs for the low-density parity-check codes in IEEE 802.15.3 standard proposal. These decoders feature by efficient hardware usage, low message memory requirement and code rate flexibility. The highly parallel level design can reach a throughput of 3.6 Gbps, which fulfills the standard requirement by processing 72 columns and 72 rows in parallel. The low...
